Abstract (en)
[origin: WO2012059481A1] The system for securing the shaft of an exhaust gas turbocharger comprises a housing element (2) designed as a retaining ring with a central opening and a radial projection on the shaft (1). The retaining ring (2) is provided with an inner contour (22, 24) in the region of the central opening. The radial projection on the shaft is provided with an outer contour (11, 12). The inner contour on the retaining ring (2) and the outer contour on the shaft are designed so as to match, such that the radially outwardly projecting projection on the shaft can be pushed in the axial direction through the central opening in the housing element (2) in at least one specific angular position of the shaft relative to the housing when the shaft and the turbine wheel (4) that is connected thereto are assembled, whereas the outwardly projecting projection bears against the housing element (2) with the central opening in the axial direction in any angular position other than the at least one specific angular position of the shaft relative to the housing. The advantage of the device according to the invention lies in the simple assembly and disassembly of the shaft (1) at a standstill. The shaft-securing system is active only in the event of a rupture. The device does not affect the rotating behavior of the rotor during normal operation.
